Based on some previous experience, the vendor's scenarios were to get the db down at cruise flight as that is where most of the time is spent. From what I was told, there are to many variables to try and get a perfect cabin in all flight phases. There are typical areas that are known problem...

I recently have picked up a measuring mic and going down the rabbit hole of improvement to my room. I work in the commercial and corporate aircraft maintenance side of the world. We just had a customer approach us about options to lower the db in the cabin of their aircraft that has some...

Good stuff. Thanks for guide link. Have been reading the help info and slowly starting to understand.

So as I continue to try and educate myself and run more testing, I have more questions....imagine that. I decided to run future tests with the mic turned to vertical and changed to the appropriate calibration file. I have attached my latest file as well as a waterfall graph. I have been...

Thanks for the information. Ran out of battery on the lasp top tonight and wart causes way to much interference. Also got frustrated trying some different positions. Haven't experimented with RTA yet and PN. Will educate myself and go from there

Agree. Thinking i will start with movements of around 6" to see if we can find a happy medium. Had played around a bit with moving speaker angles but didn't really notice much of a change. Am finding that it takes some patience and moving around of just not the speakers but the seat as well...

Moved speakers back 3 ft to within 2 feet of front wall and also moved listening position the same amount. Seems to addressed the lower frequency issue although introduced some drop in other area's although the trade off is favorable I think. Played around a bit with some futon cushions to see...

Attached file. Also, yesterday i started moving around speakers and taking measurements. When I move speakers closer to front wall, the 45-60hz drop seemed to lessen but as soon as I moved the chair up to get best imaging the drop came right back. Also for fun, generated a 45hz tone from each...

Also, image of room for visual representation of the outcrop

Newbie with a couple of other posts. Looking for advise on a couple of fronts which I will explain below. Didn't have much information in first two posts so here we go. See attached for room information. The room consist of concrete floor with carpet, one wall is concrete and entire room is...

Just getting into learning how to take readings, interpret and address things in my listening area. Once I know I am on the right track I plan on doing a bit of a novel to seek input. In the mean time I have taken some initial measurements and was hoping for any input on if folks see something...

Thanks for this. My ignorance but if at a particular preamp volume setting, I would think the output would be the same.? I am going to experiment more tonight and maybe take some actual readings. My setup is 4 tube preamp and two amps in mono format. A Schiit Freya and two Vidar's. If I...

I just got required equipment and setting up to take measurements in my listening room built last winter. This is a 2 speaker setup. I am using mic jack to rca cable from pc and a minidsp umik1 . I was able to produce pink noise to try and set level using preamp volume control. Do I need to...

New kid (actually older fella) saying hello from mid Maine. I suspect in the coming days I will be reaching out for some tech advise related to Room measuring as I have some equipment in bound. Few years back got back into vinyl so that started the endless road to perfection. Last year I...
